I’ve not experienced this, Michael. Although I’ve been to the northern hemisphere in winter I’ve yet to see a scene such as this… I do find it fascinating that water can solidify mid stream. To see Niagara Falls in this state, as an example, would be beyond imagination.
Just to give a little perspective – It will reach 41C today in my neck of Oz – Way too hot.

Flowing water freezes from the bottom up, during extended cold spells. These are becoming less frequent…climate change is not a myth. We were fortunate to view the glaciers of South America. Good to hear from you Carolyn.
